【産業上の利用分野】本発明は、竿体の内部に釣糸を通
す中通し竿に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod for passing fishing line inside a rod body.

がスムーズに行い難くなり易い。2. Description of the Related Art In a fishing line, a fishing line passes through a fishing line passage provided inside the rod body when the fishing line is fed and wound. At this time, the fishing line comes into contact with the inner surface of the fishing line passage and receives a sliding resistance, which makes it difficult to smoothly feed and wind the fishing line.
【０００３】そこで、このような摺動抵抗を少なくする

In the gazette, a guide ring made of a linear body having a circular cross section,
A technique of embedding a part of the fishing line passage in the inner periphery of the fishing line passage is shown. A technique for arranging similar linear bodies in a spiral shape is also shown. Here, it is intended to reduce the sliding resistance by supporting the fishing line with a linear body having a circular cross section.

も生じる。However, this technique has a problem that the linear body is easily separated from the rod body by the force applied from the fishing line because only a part of the linear body is embedded in the rod body. That is, since the linear body having a circular cross section and the fishing line having a circular cross section are in point contact with each other, a large stress is generated at the contact point, and the linear body is easily detached. Further, when a large stress occurs, there is a problem that the linear body or the fishing line is worn out and the durability of the fishing line is deteriorated.

釣糸の支持構造として利用する。As a technique for solving such a problem, there is a technique disclosed in Japanese Utility Model Laid-Open No. 5-88259. In this technique, a resin tape is spirally wound around a mandrel used when manufacturing a rod body with fiber reinforced resin, and a prepreg is wound on the mandrel and fired, and the resin is applied from the inner surface of the produced rod body. By removing the tape, spiral band-shaped irregularities are formed on the inner surface of the rod body. The convex portion of the spiral belt-shaped unevenness is used as a fishing line support structure.

る。凸部の先端面にはある程度の面積があるので釣糸と

応力が発生するのを防止できる。[0006] In this technique, since the spiral band-shaped convex portion, which is the fishing line support structure, is integrally formed of the same material as the rod body, the convex portion is unlikely to come off the rod body and has excellent durability. Since the tip surface of the convex portion has a certain area, the contact area with the fishing line is appropriate, and it is possible to prevent excessive contact stress from occurring in the convex portion and the fishing line.

剥がれたり変形したりすることがある。In the technique using the spiral band-shaped convex portion described above, the fishing line supporting function greatly differs depending on the arrangement shape of the spiral band-shaped convex portion. Depending on the shape of the convex portion, the contact resistance with respect to the fishing line becomes excessive and the fishing line is easily damaged. Even if the protrusion is integrally formed with the rod body, it may be peeled off or deformed from the main body of the rod body if the contact resistance force exerted by the fishing line is excessive or it is used for a long period of time. .

損傷を防いで耐久性を高めることにある。An object of the present invention is to sufficiently reduce the contact resistance with respect to the fishing line, prevent damage to the fishing line and the fishing line support structure, and improve durability.

っても釣糸支持突条が剥がれたり損傷したりし難い。In the medium-length fishing rod of the invention 1, since the fishing line supporting ridge in the form of a spiral band is integrally molded with the rod body by the fiber reinforced resin, the fishing line supporting ridge is manufactured as compared with the case where the fishing line supporting ridge is formed by another member. It is easy, and even if a contact resistance force from the fishing line is applied, the fishing line supporting ridge is not easily peeled off or damaged.

を防げる。Since the fishing line supporting ridge has a trapezoidal cross section, mechanical strength and deformation resistance are improved as compared with the case where the fishing line supporting ridge has a rectangular cross section, and peeling and damage of the fishing line supporting ridge can be prevented. Also,
Since the fishing line comes into contact with the flat surface of the upper side of the trapezoidal cross section and the contact length with the fishing line is appropriately secured, the stress generated at the contact point is smaller than that in the case of point contact. As a result, wear on the contact points is reduced, and damage to the fishing line due to excessive stress can be prevented.

まり耐久性が向上する。Since the upper surface of the trapezoidal cross section has the arcuate portion at the corner, it is possible to prevent the fishing line from coming into contact with the corner and damaging the fishing line, or conversely, chipping the corner. Further, since the contact between the fishing line supporting ridge and the fishing line becomes smooth, the contact resistance is reduced, and the fishing line can be easily fed and wound up. In the fishing rod according to the second aspect of the invention, the fishing line supporting ridge has an arcuate portion at the lower corner portion of the trapezoidal cross section. When a contact resistance force from the fishing line is applied to the fishing line supporting ridge, a large stress is generated in the lower side corner portion. Therefore, if an arcuate portion is provided in the lower side corner portion where the large stress is generated, stress concentration is relieved, and the fishing line is The mechanical strength of the supporting ridges is increased and the durability is improved.

増えて釣糸の繰り出しや巻き上げが行い難くなる。According to the third aspect of the invention, since the width of the lower side of the trapezoidal cross section of the fishing line supporting ridge is 0.6 to 1.2 mm, the area of the connecting portion between the fishing line supporting ridge and the rod body is appropriate. Therefore, the strength and durability of the fishing line support ridge are improved. If the width of the lower side is too narrow, the strength and durability of the fishing line supporting ridge will be reduced. On the contrary, if the width of the lower side is too wide, the width of the upper side of the trapezoidal cross section also increases, which increases the contact resistance with the fishing line and makes it difficult to feed or wind the fishing line.

る抵抗力を増やすことになる。According to the fourth aspect of the invention, since the height of the trapezoidal cross section of the fishing line supporting ridge is 0.2 to 0.6 mm, the fishing line is set at an appropriate distance from the inner surface of the fishing line passage of the rod body. Good support. If the fishing line support ridge is too high, the internal space of the fishing line passage becomes narrow, and it becomes difficult for the fishing line to pass through. Further, in the case of the swing-out rod, the rod bodies in front of the rod bodies are housed in the rod bodies of the respective stages, so that if the internal space of the rod body is small, the accommodation of the rod bodies of the respective stages will be hindered. When the fishing line support ridge is too low, when wet fishing line passes, water will be accumulated between the inner surface of the fishing line passage between the fishing line support ridges and the fishing line to cause resistance to movement of the fishing line. , It becomes difficult to feed or wind the fishing line. Even if the fishing line is not wet, the moving fishing line swings and comes into contact with the inner surface of the fishing line passage, increasing the resistance to the fishing line.

製するのは困難である。In the fishing rod according to the fifth aspect of the invention, since the spiral belt-shaped lead angle of the fishing line supporting ridge is 50 ° or less, the fishing line can be smoothly passed. If the lead angle is too large, the contact length with the fishing line is extended and the contact resistance is increased. In particular, when the fishing line is wet, the water existing in the contact portion produces a resistance force, and thus the contact resistance increases as the contact length increases. Further, it is difficult to manufacture the fishing line supporting ridge with a large lead angle in terms of manufacturing technology.

Further, during manufacturing, it is difficult to generate fluff during the operation of winding the reinforcing fiber. In the medium-length fishing rod of the invention 7, since the fiber-reinforced resin forming the fishing line supporting ridge has a volume content of the reinforcing fibers with respect to the resin of 50 to 70%, abrasion resistance is high and sufficient strength can be exhibited. If the volume content of the reinforcing fibers is less than 50%, the abrasion resistance becomes low, and 7
If it exceeds 0%, the adhesiveness between the fiber-reinforced resin forming the fishing line supporting ridges and the fiber-reinforced resin forming the main body of the rod body deteriorates.

The prepreg layers 120 to 126 are directly arranged on the outer periphery of 14 without a release tape. The subsequent steps are the same as in Manufacturing Example 1 above. In Production Example 2 described above, the release tapes 112 and 116 are not required as compared with Production Example 1, so the production process is simplified. However, since the ridge tape 114 and the prepreg layer 120 are in direct contact with each other, a ridge tape 114 having good releasability is used.

Water repellency is improved. By subjecting the ridge tape 114 to a surface treatment, the surface of the prepreg layer 120 with which the ridge tape 114 comes into contact, that is, the surface of the fishing line passage 15 in the valley portion formed between the fishing line supporting ridges 40 can be made hydrophilic. . By doing so, the water flows along the troughs of the fishing line passage 15 having hydrophilicity, so that the water that has penetrated into the rod body 14 can be discharged well.
